.PATENT ppm JOHN SCHADE, OF HOLYOKE, MAssACHUsE'rTs AssIefNoxaro NATrONAr BLANK BOOK COMPANY, or HOLYOKE, MASSACHUSETTS, A. CORPORATION or .NuissACnUsE'rTsV LOOSE-LEAF BOOK' `Application filed- June 1, 192s: serial No. 282,090;

\ lThis invention relates to loose le'afbooks, but has particular reference to'books of this nature that have their side covers connected to some part of the structure by metal 5 hinges.

Heretofore the side covers have been secured tothe book back-structure byv metal hinge elements, as is shown and described in patents issued tome asfollows: No. 1,478,-

issued September 16, "1924, No; 1,508,821, issued September 16,1924, N o. 1,512,488, issued 0010106121, 1924, N0.*1,512,1e9, issued October 21, 1,924, No. 1",540,228,'issued June 2, 1925, No. 1,548,332, issued August 4,` 1925, p and No.'1,r557,883, issuedOctober 20, 1925.

In all the constructions shown in these patents anl intermediate metal back plate was employed which wasv hinged along its side edges to? the inner edges of` theside covers, and this back plate served as the bottom plate ofthe loose leaf mechanism, and said backplate wasV covered as afgeneral practice with anouter back plate faced with leather that corresponded in `color and pattern with the color and'pattern of theside covers. Y f

It is the Obj ect of the present invention to eliminate this intermediate metal back plate,

.30 by hinging theside` covers directly to the cover plate of the loose leafv mechanism, so that the latter and therside covers shall constitute an entirety separate from the back of the book, and then to, apply the book back 3.5 directly to the loose leaf structure, this back being either made ofV metal covered with leather, cloth or other material colored and patterned? to give thedesired artistic effect, or shaped from vulcanized fiber or other suitable nonlmetallic substance, the back in either formgcarrying fastening devices for attaching same tothe loose leaf structure.

The accompanying drawings illustrate some of the ways in which the invention may be carried out, and in these drawings Figure 1 is an inside view of a loose leaf book with the side covers Opened and `hinged to the cover plate.'`

Similar numerals ofreference denote like parts in the several igures of the drawing.

Referring to Figures 1 2, 3, 4, 5, and 12, 1 is the coverv plate casing which isblanked out with spaced ingers2 extendingI laterally from its side edges as shown at Figure 12, and the side edges of the cover plates are bent downwardly and inwardly shown at 8 to form the retaining abutments 4 for the plates 5 that are pivotally connected at their inner edges and that carry the loose leaf prong members 6.

After the side edges of the cover plate have been bent in the manner above described the lingers 2 are bent upwardly in contact with these anges 3 and then formed into eyes 7, this construction being quite advantageous in that the flanges 3 are of double thickness.

The form of loose leaf structure comprising the pivoted pla-tes 5 and prongs 6, and the operation of these plates within the cover plate casing are well known and are illustrated in many prior patents and no further detailed description of these parts will be entered into herein. All that is necessary is that the cover plate shall be so formed at its side edges that the side covers 8 may be hinged thereto, usually by means of eyes 9 carried in spaced relation by the inner edges of the covers and interengaged with the eyes 7 and a pintle 10 passed through both sets of eyes, and to complete the book a separate back 11 preferably having long eyelets 12 extending from its inner tace, is applied directly to the structure shown at Figure 3, these eyelets passing freely through openings 13 formed in the plates 5 and perforations 14 in the cover plate, the ends of these eyelets being then spun over or set against the cover plate as shown at 15.

This back 11 is preferably made of vulcanized fiber with the eyelets 12 or other analogous devices securely anchored at the bases within the substance of the fiber, and the latter is colored and patterned to conform artistically to the color and pattern of the side covers.

This back may be made of bakelite with the eyelets anchored therein, or it may be made of meta-l covered with cloth or leather, but in all instances the back is suitably shaped and conformed in color and pattern to agree artistically with the color and pattern of the side covers.

rl`hese hinge eyes along the side edges of the cover plate may be formed in many ways, some of which are illustrated herein and will now be referred to.

In Figure 6 hinge eyes 16 are lanced out of the cover plate and after bending into the form of eyes have their free ends extending inwardly as shown at 17 to provide flanges similar to the flanges 3, as shown particularly at Figures 7 and 8.

Or the fingers shown in the construction at Figure 12 may be bent downwardly into the form of eyes 18 as shown at Figure 15, the extremities of these fingers extending inwardly below the cover plate so as to form rests a for the plates 5.

Or these fingers after being bent to forni the eyes 18 may extend downwardly as shown at Figure 14, to provide the flanges 3a.

Or, the side edges of the cover plate inside the bases of the fingers may be bent downwardly and inwardly to form the flanges as shown at 19 in Figure 16, and the fingers curled around upwardly to form the eyes 20.

Or', the edges of the cover plate may be bent downwardly and inwardly to form the flanges 4, as at Figure 5, and spaced per forations 24 made in the terminals of said edges, theviingers 25 that form the eyes on the covers being inserted through these perforations and curled around to form eyes 26, as shown particularly at Figures 17 and 18, this manner of hinging being shown in my Patent No. 1,557,883, aforesaid.

It will therefore be readily understood that the manner of forming these eyes at the side edges of the cover plate is immaterial, the gist of the invention in this respect resting in the broad idea of providing spaced hinge eyes at the sides of the cover plate so that the side covers may be hinged directly thereto.

The advantages of the construction hereinbefore described are quite important, in that the side covers have nothing whatever to do with the back and can be assembled on the cover plate in connection with the loose leaf mechanism, so that it is merely necessary to apply the back plate without any intermediate metal plate whatsoever.

This invention lends itself admirably to a loose leaf structure in which boosters are used for the purpose of opening the prong members, and referring to Figures 9, 10, and 11, this will be apparent.

In Figure 11 the side covers and cover plate are extended beyond the lines of hinging, and the booster clips 21 embrace the free ends of the cover plate, while flaps 22 are extended from the side covers across the rear end portions of the cover plate and parts carried thereby, these flaps being secured together in any suitable manner' as by metal clips 23, this construction of the side covers being shown and described in my patent aforesaid No. 1,540,228.

A bool: constructed in this manner so that it appears when viewed in the rear as is shown at Figure 11, would be somewhat unsightly unless provided with a back such as has been heretofore described, but when the back is applied the book will appear at the rear as is shown at Figure 10 and on the inside as is shown at Figure 9.

It is a fact that the constructions heretofore described would be just as serviceable without a back as they would be with a back, although they would not have commercial value without the back, nevertheless, all the mechanical functions and utilities of the book Would be present Without the back, and this invention is therefore an innovation in that the side covers are hinged directly to the cover plate. 1

When the back is applied there is no metal plate intermediate between the back and the loose leaf 'mechanisnn and the Completed book is therefore both greatly simplified and lightenedV Without detracting from its strength appearance.

What is claimed is The hereindescribed improvement in loose leaf books, comprising side covers, a metallic cover plate casing, prong carrying members housed Within said easing, the sides of said casing having hinged connection With the inner edges of said covers, and a separate rigid back applied in the immediate rear of said members and secured to the cover casing.
